Lt. Andy Neiman, an LAPD spokesman, tells the Los Angeles Times, "The whole idea is just to re-message the theme of avoiding the 405 area and that it's going to be a mess if people don't stay away...

"Twitter is a way to reach that whole demographic that could be oblivious to the 405 closure for that weekend."

Gaga, Kutcher, his wife Demi Moore and Kim Kardashian have all been asked to join the Twitter campaign, while former "CHiPs" star Erik Estrada has filmed a public service announcement about the closure.
